The 2010 Rectifier is a fuckin' beast Need I say more? It sounds really tight and aggressive compared to the other 3 channels I've played. This is my first 10 minutes with the amp, so be kind
EDIT FOR SINGLE MIC'D CLIPS FOR BOTH (NO MORE FREDMAN)
Here is a comparison of the 2010 Recto (single mic'd) and Racktifier (single mic'd).
